ATo aZ-Zfwhom bf/ mty concern: I i Be 1t known that I-,PAUL MAUSER, royal commercial councilor, a subject of the King of Vrte1iiberg,residing at Oberndorf-onthe-Neckar, in 'the Kingdom of Wrtemand useful Improvements Relating to Re# coil-Operated Small-Arms, of which the following is a full, clear, and exact description. This invention relates to improvements in thev recoil-loadingrile having a movable barrel shown-and described in specification of Patent No. 783123.

According .to thepresent invention, provide a. rotary sleeve which is open at its rear 5 end to permit the insertion of the firing pin,

vand which i'sprovided with a closure against `vhich the Aliring "pin-Spring re acts Sil-Ch closure being-prov-ided-with an elongated i This vknob or handle is adapted to connect orv knob and forms opened by hand to extract it, there is nopin formingla guide for the ,firing pin very greatly fa' spring. "This construction cilitates v the assembling of the-parts.

' Iii-fa construction of the aforesaid patent,

the weapon iS. provided witha knob Orhandle or adjusting the weapon for use either as a magazine loader or as asingle loader.-

disconnect the propelling spring for the breech bolt. In this construction a sleeve is provided which is connectedwith the a guide or casing for the breech bolt. According to iny present irivention, I'utilize such sleeve to provide an auxiliary means for withdrawing 'the-- fire" pin to aslightextent so that rit does not protrude from the bolt head. By this means if a cartridge lmisses fire and the breech is dangerl ofthe firing -pin coming in contact with the percussion cap of the cartridge so that accidental. explosion is prevented.

The. improvements which form the subject matter of the present invention -are illustrated the accompanying drawings. `Figure. l shows the lock of the recoil loading rifle, partially in section, in the locked position, that is to say, with the breechA i piece bolted or locked andthe knob. or lian- 'dle turned down into the 'position for magazine loading.

Thisl closureis moreover lfurnished with a pin u1 which projectsinto the recess '81* of the firing pin s and* 901'v 'rier of thev rotary sleeve AQ. The rear part." of the sleeve is closed bythe closure u, which' as already'mention'ed, forms a bearing for into the recess s1' of the ring pin s, ATl1isf being effected the closure novercoming theresistance of the 'firing pin spring t, 1s forced '-10.9 stand opposite tothe slots ai2 of the sleeve manner of a.bayo iiet joint byf rotation-x." .through an angleof 180.

I/Vhe'n this -k'nob is turned vinto the orizontal i position, which. yoccurs when the reech is -to be opened by hand, the V'connec- ,on between the barrel'and its forwardly ropelling spring isfinterrupted while when ie. hand knob is turned into a vertical' posion, 'the'spring;.F is coupled to, the bari-el. The rear end'of the sleeve nl has an obqu'e end no against which there bears a proacti'on fvl, thatextends laterally. from the lot-ted part/v, bymeaiis of which the arrest# ig leverE'is pivoted in the usual 4manner n; the'rear end of the .firingpin 'As may be,l een from Fig. '3,'.,the'l poi-nt of the firing pin,y is'in this manner withdrawn behind the fore nd of thebolthead 7 by the action of. the blique end n' ofthe `sleeve n1, when the reech is opened by hand, that is to say, when theknoh N1 is' brought into'thelioriontal positiofu A s already mentioned, this esults.'in' the important advantage that in he event'of a-mis'firev preceding the openng of the breech, the point of the firing pin s withdrawn from .the percussion cap while he cham-ber is still closed, so that even if the artridge sh'ouldvexplode during the u nlockng of thel breech bolt, no injury would hereby be inflicted upon the user of the rifle,

vs the breechl wouldstill be closed.` The fact hat the, point ofy th'efir-ing pin is, during lie opening ofthe breech, removedv from the L considerable'distance, and which, when thev )reechpiece is in the position referred to, enters the imaga-Zineand becomes engaged )ehind the edge of the uppermost cartridge. Even if the'cartridge lies at a somewhat ower level than 'usual4 it consequently means of its projection r1 which grips the cartridge, not only close to its edge, but even somewhat lower, down and the cartridge will thus under allcircumstances' be firmly held 'and introduced into the cartridge chamber. -It is therefore absolutely 4impossible for the4 cartridge not to be caught by the bolt head or toslip away .from it, and there is no necessity for employingv a bolt head of larger dimensions than usual.

lVhat I claim as my invention, and desire to'secure by Letters Patent is:

l. In an automatic ire arm, the combinationof a tiring pin, a carrier for the latter comprisingv a rotary sleeve and aclosure for said4 sleeve, said sleeve 'having internal -re'cesse's and said closure having external projections adapted to vtitsaid recesses, said sleeve being adapted to permit the insertion of said closure in one position and said 'closure being adapted to tu'rn until its projections are opposite said recesses, and to engage the same by a rearward movement of said closure.. f'

2; In an automatic fire arin, the combinationi of a firing pin, a carrier for the latter 'comprising a rotary sleeve and a closure for said.l sleeve, said sleeve having internal recesses and` said closure having external prostill be 'caught hold of by the jec'tions adapted .to tit said recesses, said;

sleeve being adapted to permitl the insertion o f said closurein oneposition and said closure being adapted to turn until its projections are opposite said recesses, and toen- `gage thesame'by a rearward movement of said closure, said firing pin having a spring g and said closure having a forwardly extenduide for s aid spring.'

ing pin .serving as a 3. In an automatic re arm having a'movable breech bolt, a firing-pin, and means for moving -said breech bolt and cockingjsaid tiring pin, an auxiliary means for withdrawing said firing pin within the breech boltwhen the latter is opened so asto avoid 'accidental explosionv of` the cartridge, said last named means comprising a projection c" carried by .theliring pin, said projection having a lateral shoulder v1, and a sleeve nl having an oblique face no on its rear end anda handle for turning saidsleeve, whereby said obliqueface acts upon the shoulder v1 to withdraw the tiring pin.

In witness whereof, I have hereunto signed my name in the .presence of two subscribing witnesses. PAULMAUSER.
